To all whom t may concern: hereinafter full described and pointed out Beit known that I, EUGNE LEcocQ, a in the appendedY claims. sub'ect of theKing of Belgium, residing The annexed drawings show by way of atrussels, in thc Kingdom of Bel ium, example a coke oven constructedaccording have invented certain new and usefu Im? to my invention.

It is evident that vthe erationassuring the maximum economy and number of regenerators provlded in asircilgle 105 diminishing the. heat lost by radiation and group and foreach oven can be varied. e conductii. two ducts 9 of two groups ofregenerators l ith these objectsin view my invention coperating with asingle furnace, ducts essentially consists in the special arrangewhichare arranged in the same axisas that ments and combinations of parts aswill be of the corresponding combustion chamber 2, 110

are in communication with the under conduit 15 arranged parallel in theHoor of the oven and extending the length thereof. Two of these adjacentconduits are connected (as shown in Fig. 4:) to the ducts 9 connected tothe regenerators of the same group, e., situated at the same side of`the gallery and also two adjacent conduits 15 are conneoted to the ducts9 in connnunication with the group of regenerators situated on the otherside. ot' the gallery (l. The conduits '15 as required distribute the.air to or collect the burnt gases from the chambers 2 by the ducts 16connected to the combustion compartments 1T in the chambers 2. The gasis distributed to each chamber by a series of ducts 1.8 connected to agas pipe v1S).

The working of the Jfurnace can be readily understood. By way of examplethe passage of the air and of the. burnt ga.C s is indi cated in. thearrangement: dest ibed. The air coming from the gallery l. li lgs. 1 andil, and having passed through the reversing apparatus 14, Fig. 3.puisses into the` collert4 ing flue` 13.

Il. arranged in series and then passes to thecorresponding duct 9 and to one of the two underneath conduits l5. Figs.*2 and l. from which 'it is distributed by the ducts 16 to the variouscompartments 1T ot" the combustion chambers. The heated air combines inthe conv partments 1T with the. gas distributed by the pipes 1S. The'nurnt passes down the vertical compartments Q1, Fig. l, into theneighboring conduits 'l5 underneath the chamber by the correspondingduct 1G and thence to the regenerators 3, 4, 5 of the seo ond group bythe course indicated by the arrows Figs. 1 and 4. After passing throughthese rcgenerators the gas entersv the second collecting Hue 13, Figs. 1and 3, and. through the reversing apparatus 14: to the chimney. Thepassage of the air and gases is then reversed, the air passing in the opposite direction through all the ducts and compartments previouslytraversed by the burnt gases.

On examining the drawings it is seen that owing to the arrangement ofthe regeneretors all the structure of the oven is conveniently supportedby the moreover owing to the arran ment of the regenerators in the axisO t e combustion chambers the height of the structure is oonsiderablyreduced as the lateral space neu-.ssary for the underneath conduits 15is obtained without adding to the hei ht of this part of the structure.Thel air an the burnt gases canbe easil regulated at will in eachcombustion cham r as two adjacent undermasonry and neath conduits areused for each oven, in which the air andthe gases move in the samedirection (see the direction of arrows Q3 Fig. 4) thus allowing'thepossibility otf creating an equal pressure for each compartment in thechamber and so regulating the quantity of air passing into each verticalcompartment of the combustion cham-ber.

Finally the described construction with the regenerators arranged inseries considerably decreases the heat lost by radiation and conduction.

It is evident that the invention is not liniited hy the constructiondescribed and shown and that the details can he varied. Thus for examplethe number of regcncrators in each group and for cach oven can bemore orless than three and moreover they may be arranged in parallel instead ofin series as described. A

lt will he observed that in sulldividing each transverse regenerate!" orgroup of two transverse. regcneratois cooperating with a single oveninto several separate regenerators the axes of which are vertical andwhich are formed hy rhamliers of masonry forming towers of ma nry thewhole struff ture is extremely sola and allows of ay construction muchlighter th an hitherto.

Having thus described my invention, what l claim is:

In a regenerator coke oven. the combination with a plurality of ovensand their combustion chambers having their major axes horizontallydisposed, of a support ing structure for said ovens and combos tionchambers, forming a plurality of chambers disposed directly beneath saidovens and having their major axes vertically disposed. and a regeneraiorformed in each of said last named chambers.
